You can add a customizable calculation form based on the selected parameters. To do this, add a "Calculation field" to vertical forms with multiple inputs. You can set up calculation parameters in the Quantity, Dropdown, Checkbox, and One-line input fields.
How it works
— Add a vertical form with multiple inputs from the "Form" category, e.g. BF204N, BF310N, BF311N, BF402N, BF403N, or BF502N. — Create input fields, e.g. width, length. — Assign a unique variable name to each field, e.g. "width" and "length." — Type in a calculation formula using mathematical operators such as +, -, *, /, () (e.g. "width*length") — When the customer fills out the form, calculations will be performed automatically, the result will appear in the field.
Example
A simple calculator to estimate the cost of a tabletop based on length and width.
Set the dimensions of the tabletop to find out the final price
How to create a form like the one in the example
Add a vertical form with multiple inputs to the page. Block Library → Form → BF204N.
Open the Content panel of the block by clicking on the orange button in the top left corner of the block. Add a title and description in the Block Header tab.
Create a field for a tabletop's length: — Add a One line input field. — Set a variable name. We've chosen length for this example.
Create a width field using the same method.
Create a length field
Create a width field
Create a field where the total cost of the tabletop will be calculated automatically: — Add a Calculations field. — Add a title, subtitle, and variable name; — Provide a cost calculation formula.
The formula used in the example is length*width*160, where 160 is the price per square meter.
Use only simple mathematical operators: +, -, *, /, and ().
Provide a cost calculation formula
If needed, add symbols/texts to appear before and after the calculated cost
Example of a complex order form calculator
An order form calculator with Checkbox and Dropdown fields. There are 5 parameters that will determine the final price: Material — type of wood Length — tabletop length Width — tabletop width Cover — tabletop coating Legs — type of table legs
The cost calculation formula: length*width*(material+cover)+legs.
To calculate the final price, set the following values: type of wood, size, coating, and type of legs.
